Star Refrigeration has unveiled Azanechiller 3.0, the latest evolution of its low-charge ammonia chiller, setting a new standard for industrial cooling effi ciency and sustainability.
Designed and manufactured in the UK, Azanechiller 3.0 exceeds EcoDesign energy effi ciency targets by up to 110%, using up to 52% less electricity than standard models. It outperforms UK competitors by as much as 20% in Seasonal Energy Performance Ratio (SEPR), making it the most effi cient low-charge, air-cooled ammonia chiller on the industrial market. Capable of operating across a temperature range of -20°C to +25°C and cooling capacities up to 1,600kW, the plug-and- play chiller is suitable for food processing, pharmaceuticals, data centres, ice rinks and temperature-controlled storage. Engineered for resilience, it off ers a 25+ year lifespan and robust safety features, including portable safety showers, enclosed electrics, and optional access ladders. Environmentally, the Azanechiller 3.0 is future-proof in that it is F-gas and PFAS regulation-exempt with a low ammonia charge (0.18kg/kW), and optimised for ambient temperatures up to 40°C. The system is also Ethos-ready, allowing real-time AI-based data analysis and energy optimisation. Azanechiller 3.0 aims to deliver a reliable, energy-effi cient, and sustainable cooling solution that supports businesses on their journey to Net Zero.
